  1. Initial dimensional inspection of the crankpin is undertaken by calibrated measuring instruments for taper, ovality, and other parameters.<\/li>\n\n\n\n
  2. The radius fillet, lubricating oil hole of crankpin, is checked for any loss of profile and damage.<\/li>\n\n\n\n
  3. Crack detection test by high-intensity MPI torch is undertaken by level 3 qualified technicians.<\/li>\n\n\n\n
  4. Hardness check and other important parameters are checked and recorded.<\/li>\n<\/ol>\n\n\n\n

    After the initial inspection, in case required grinding and polishing of the crankpin<\/a><\/strong> is undertaken, to maintain the tolerances strictly as per the manufacturer\u2019s specifications.<\/p>\n\n\n\n
